IMPROVED CUTTER-STOCK.

Specification forming part of Letters Patent No. 45,742, dated January3, 1865.

To all whom 'it mag concern:

Be it known that I, JOHN PEAGE, ot' Camden, :in the countyT of Camdenand State of New Jersey, have invented a new and Improved Cutter-Stockor Cutter Screws; and I do hereby declare'that the following is a full,clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference bei ng had to theaccompanying' drawings, making a part of this specification, in which-Figure 1 is a side view of my invention; Fig. 2, a section ofthe same,taken in the line a: w, Fig. l.

Similar letters of reference indicate like parts.

rlhis invention relates to a new and improved cutter-stock for cuttingscrews on gas and other pipes; and it consists in the employment or useof double cutters, fitted in a stock peculiarly constructed, ashereinafter set forth, whereby the cutters may be readily adjusted, andeither end used to operate upon pipes of different diameters, and thecutters accurately adjusted to suit the diameter of the pipe to loeacted upon.

A represents a circular head, provided at two opposite points withsockets B B to receive the handles C C of the stock. The head Aisprovided with three sockets, D, in which the cutter-bars E are iitted.These cutter-bars have a cutter, et, formed at each end of them,

and the cutter-bars may be withdrawn from the sockets D, reversed inposition, inverted, and replaced, so that either cut-ting end may beused. The cutters a of each bar E are made to operate upon pipes ot'different diameters. and each bar E has a recess or hole, b, made in itto receive a setsercw, F, to hold the bars in position, the holes orrecesses b being made at points to admit of the cutters a projectingwithin the head a distance to suit the diameter ot' the pipe to be actedupon it. (See Fig. 2.)

Vithin the head A there is a collar, G, which is securedin position by aset-screw, H. Several collars, G, having their internal diameter ofdifferent sizes, corresponding to that ot' the pipe to be operated upon,are designed to accompany each stock, and several sets of cutters E arealso to accompany each stock.

Thus it will be seen that besides adjusting the cutters to operate upondifferent-sized pipes, the cutters may be removed and sharpened with thegreatest facility and always kept in proper working order.

I claim as new and desire to secure by Letters Patent- As a new articleof manufacture, a cutterstock constructed as herein shown and described.I

JOHN PEACE.
